Transparent Network Configuration for Internet Telephony Traffic

Telephony services represent an increasing class of applications supported by the current Internet. Due to their cheapest cost, many residential users are adopting VoIP solutions. Therefore, Internet Service Providers need to plan and configure their networks to support services with Quality of Service requirements. In this paper we present a transparent and dynamic approach to the network devices configuration according to the "user traffic profile". Here, a dynamic configuration of synthetic traffic reproducing real VoIP streams is considered. Our proposal relies on the capabilities of an "intelligent node", which is able to observe the network behavior and to configure it in an efficient way.
